1 Implementable right now (but not necessarily important), with caveats
2 (unavailable components that will limit what can be implemented right
3 away), in order in which they will likely be done:
4 * TESTING-TESTBED [Nate]
9 * FRAGMENTATION [Ji Lu]
11 * MySQL / Postgres plugins (datastore, datacache)
17 * HOSTLIST/PEERINFO/CORE/TRANSPORT/TOPOLOGY:
18 - hostlist server learns about 2nd peer, but soon forgets (not
19 clear if this is still an issue, or if validation failed or
20 if this was an issue with the client's parsing of the reply, which
23 - needs more testing (especially F2F topology)
24 - needs to re-try connecting after disconnect (currently, it
25 initially triggers a connection request, but if that connection
26 fails / goes down, it does not retry in a timely fashion;
27 cause seems to be the 'blacklist_after_attempt' being set to 1h,
28 which is rather long -- and should probably be adjusted based on
29 the number of connections / known peers)
31 - peers do not seem to connect (setkey, ping are there; PONG is sent,
32 not sure what else happens; eventually, the "neighbour" entry times
35 - load: need way to determine network load (up/down) -- and quickly so!
36 - trust: need *fast* way to check/update trust in peers
37 (async peerinfo would not be right)
38 - scheduler should change OS process priority based on task priority;
39 should make better use of task priorities in general
41 - disconnect notifications from TCP not always as nice as we might want
42 them to be (but how can we do this cleanly given that UDP is connectionless?)
43 - TCP not used bi-directionally (especially important also for PONG!)
44 Need a way for plugin to tell to service that it can *reliably* transmit
45 PONGs. Need *good* way to ensure only one (plugin) session is active at
46 any given point in time; need systematic way to periodically probe latency/
47 transport cost changes
48 - hostlist testcase shows that (randomly) we jump to an address that
49 seems to be a plugin function *after* the plugin has been unloaded
50 (directly from scheduler); check that *all* plugin tasks are cancelled
51 after plugin is unloaded! (need better testcases for that...)
53 - synchronous/asynchronous API (& implementation) is not nice;
54 => provide notification-based API
55 - does not seem to work with timeouts (especially if service is not running)
57 - add stats (# bytes available, # bytes used, # PUTs, # GETs, # GETs satisfied)
59 - need to get rid of synchronous API for service starts (cause all kinds of problems)
60 [=> eliminate for need to tell ARM about service starts most of the time!] [Safey]
62 - need function to test "equivalency" of HELLOs; use in topology!
64 - gnunet-publish cannot be aborted using CTRL-C
65 - gnunet-publish segfaults if file does not exist
66 - on some systems, keyword search does not find locally published content
67 (need testcase of command-line tools!)
68 - 2-peer download is still too slow (why?)
69 * Module features to implement:
70 - advanced FS API parts
71 + namespaces: fundamental namespace API
72 + search: SBlocks, KSBlocks, probes, notify FS-service of known results
74 + location URIs (publish, search, download)
75 + persistence support (publish, unindex, search, download)
76 + indexing: index-failure-cleanup
77 + download: management/bounding of parallel downloads (for recursive dl.)
78 + datastore reservation (publishing)
79 + gnunet-publish (URI args)
80 + gnunet-download (directory)
81 + gnunet-search (options, incl. namespace search)
82 + gnunet-download (many options)
83 + gnunet-directory (man page, options)
84 + gnunet-pseudonym (all of it)
85 + gnunet-service-fs (remove failing on-demand blocks, stats, hot-path routing, load-based routing, nitpicks)
86 + datastore: do active migration support here?
87 - implement adv. FS testcases
89 + insert: sblocks, loc uris
91 + search: sblocks, skblocks, loc uris
94 - implement FS performance tests (needs TESTING)
99 - non-anonymous FS service (needs DHT)
100 + basic DHT integration
101 + CS-DHT-functions (DHT-put of LOC)
102 + P2P-functions (DHT-get)
105 + need to settle basic design; do we want to keep guile?
107 + modify configuration to allow controlling connections for non-local starts
108 + testbed creation with topology (needs working F2F topology) [Nate]
109 + testbed with churn [Nate]
110 + implement library for distributed testing [Nate]
111 + implement testcases for distributed testing [Nate]
112 + test basic peer re-configure [Nate]
113 + test topology creation [Nate]
114 + test churn generation [Nate]
120 * Module features to implement:
122 + good to have for DV evaluation!
125 + implement DV service [Nate & CG]
126 + implement DV library [Nate]
127 + implement DV transport plugin [Nate & CG]
128 + implement testcases [Nate]
129 + implement performance tests [Nate]
132 + how to integrate scheduler with GTK event loop!
135 * Module features to implement:
137 + good to have for DV/DHT evaluation!
139 + implement DHT service (needs DV, DATACACHE)
140 + implement DHT library
141 + implement testcases
142 + implement performance tests
145 * Plugins to implement:

154 + see discussions @ FISL about integration with event loop!
155 * Determine RC bugs and fix those!
160 - update webpage documentation
162 - expand bibliography
163 - convert documentation pages to books
164 - update books (especially for developers)
165 - create good Drupal theme for GNUnet
166 - make a NICE download page and figure out how to
167 enable developers to publish TGZs nicely
168 - port "contact" page
169 - add content type for "todo" items?
171 * Plugins to implement:
172 - MySQL database backends

179 * Determine RC bugs and fix those!
183 * Plugins to implement:
184 - SMTP transport backend

188 * Remove KBlocks in gnunet-unindex (see discussion with Kenneth Almquist on gnunet-devs in 9/2009)
189 * Allow checking of presence of search results and/or content via command-line tools
190 (add options to gnunet-search / gnunet-download to limit search to local peer)
192 - should use BIO instead of mmap
194 - expire 'ancient' HELLOs (those without valid addresses AND that
195 we have not 'used' (for their public keys) in a while; need a way
196 to track actual 'use')
197 - make sue we also trigger notifications whenever HELLOs expire
